That is, after the voice signals of the other party are received through the tablet terminal 100, the voice signals of the other party are outputted through the user interface 218 of the portable terminal 200, and the voice signals that are generated via the user interface 218 of the portable terminal 200 are transmitted to the other party through the tablet terminal 100.
  • A method for a call termination in step S208 may be performed as follows.
  • First, in case where the portable terminal 200 makes the call termination, the portable terminal 200 generates a call termination message in step S210, and then provides it to the tablet terminal 100 through the synchronization module 212 in step S212. Accordingly, the tablet terminal 100 terminates the call connection with the caller via the short-range communication module 110 in step S214.
  • On the other hand, in case where the tablet terminal 100 makes the call termination, the tablet terminal 100 terminates the call connection with the caller's terminal which is made through the wireless communication module 110 in step S216, creates a call termination message in step S218, and then provides call termination message to the portable terminal 200 through the synchronization module 112 in step S220. Accordingly, the call connection is terminated between the tablet terminal 100 and the portable terminal 200 while maintaining the linkage therebetween.
  • The embodiment of the present invention may also conduct a request for a call connection from the portable terminal 200 as follows.
  • First of all, the tablet terminal 100 determines whether or not a request for a call connection is received from the portable terminal 200. When the call connection request is received from the portable terminal 200, the tablet terminal 100 requests the call connection with a wireless network 300. After making the call connection with the wireless network 300, the tablet terminal 100 transmits voice signals generated by the portable terminal 200 to the wireless network 300 and transmitting voice signals received from the wireless network 300 to the portable terminal 200. Thereafter, upon terminating the call connection with the wireless network 300, the tablet terminal 100 terminates the communication with the portable terminal 200.
  • As set for the above, in accordance with the embodiments of the present invention, by providing the phone function of the tablet terminal by means of the portable terminal via communication between the tablet terminal and the portable terminal, it is possible to implement the phone function, which is inconvenient to use because of the weight and size of the tablet terminal, by the use of the portable terminal, and do an internet search, read e-books, or the like on a relatively large screen by the direct use of the tablet terminal, thereby increasing user convenience.
  • While embodiments have been shown and described, they are not limited thereto. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
